White line appears at top of framed iPad A16 videos

[brunodelgado]

Hi! I'm seeing an issue when using Frames CLI to add a device frame to videos recorded on an iPad A16.

When I frame a screen recording video from this device, the generated framed video contains a thin white horizontal line at the top of the screen/content area. The line appears inside the device frame, along the top edge of the video.

This only seems to happen with videos recorded on this device.
Framed screenshots from the same device do not show the white line.

Here's a comparison of the framed video and the framed screenshot:

1640 × 2360 • 89.78s • hevc, audio: aac
✓ iPad Air 2020 Portrait
  Frame size: 1921x2640
  Color: none

✓ iPad Air 2020 Landscape
  No color variants

Steps to reproduce

1. Record a screen video on an iPad A16.
2. Run Frames CLI to add a frame to the video.
3. Open the generated framed video.
4. Notice a thin white horizontal line at the top of the video content.

Expected behavior

The framed video should not have a white line at the top. It should look clean, like framed screenshots from the same device.

Actual behavior

A thin white horizontal line appears at the top of the framed video content.

Notes

• This happens with video input, not screenshot input.
• The video is detected as iPad Air 2020 Portrait.
• The screenshot is detected as iPad Air 2020 Landscape.
• The actual device used is an iPad A16.
• I'm not sure if the detected frame/device mismatch is related, but I wanted to include the frames video-info and frames info output in case it helps.

Environment

• Device: iPad A16
• Input video resolution: 1640 × 2360
• Codec: hevc
• Audio: aac
• Frames CLI version: 1.3.0
• OS: 26.5.1
• Command used to generate framed video: frames video

Thanks!
